Seen from the hill．the city looks beautiful. ·-ed分词和逻辑主语之间关系是被动的。 (2)当从句的主语与主句的主语一致时，常将从句中的主语和助动词省去，只留下从属连词和-ed分词短语，在句中分别作时间状语、原因状语和条件状语等。常见的从属连词有：if，as，though，unless，until，when，while，as if，once，whenever。 例：Though still practised today，the tea ceremony may not be as popular as it used to be. Don’t do it unless asked. lf caught cheating，the student would be punished When heated，ice will be changed into water (3)-ed分同做伴随状语、原因状语。 例：The girl he rd the bad news and went away, disappointed. Greatly encouraged by the teacher，she made great progress in English. (4)-ed分词用于独立主格结构。 有时由名词通格／代词主格加上-ed分词构成独立主格结构。这种结构多用来表示行为方式或伴随状况．有时用来表示时间、原因、条件等。这时-ed分词与前面的名词通格／代词主格之间是被动的逻辑关系。 例：The homework finished =When the homework was finished), the child went to bed. He rushed into the room, his face covered with sweat. With+宾语+-ed分词．表伴随。 例：She sat with her head bent All afternoon he worked with the door locked. (5)否定式为not十-ed分词。 例：Not worried by his failure．he went on experimenting. ·作定语 与动词不定式、动名词及现在分词相比，同样作为非谓语的-ed分词其形式是单一固定的：done(以动词do为例)。其表达的意义经常是被动或完成或二者兼而有之。 例：The stolen money was returned to the owner soon. The bridge built last year is modern. (划线部分为过去分词和过去分词短语，既表示被动又表示完成．分别作前置和后置定语。) (1) 现在分词、过去分词和不定式被动式作定语时的区别。 现在分词表示主动，过去分词表示被动且动作已完成。不定式被动式表示被动而动作未完成。 例：China is one of the developing countries in the world, as is known to all. Tile houses damaged in the flood have been rebuilt. There will be a concert to be held in the hall e tonight (2)现在分词的被动形式与过去分词表示被动的区别。 现在分词的被动形式表示正在被执行的事．过去分词表示已发生过的或已被完成的动作。 例：A lot of high-rises being built can be seen in the city of Shanghai 在上海，处处可见正在建造中的摩天大楼。 The World Cup held in the Republic of Korea and Japan was a successful one. 在日韩举办的世界杯是成功的。 2．experience的用法 ·n .【U】（he gaining of) knowledge or skill from practice rather than from books经验．体 ... ...
